AIM
We report our experience with the use of 1.7 mm 3-dimentional (3D) strut plate for the management of mandibular angle fractures.
METHODS
This prospective study enrolled 15 patients in whom mandibular angle fractures were treated with 1.7 mm 3D plate using trans-buccal trochar. Patients were evaluated at 72 h, 2 weeks, 6 weeks and 12 weeks for fracture stability, occlusion, soft-tissue swelling, infection and post-operative inferior alveolar nerve damage. Other complications like wound dehiscence, non-union, mal-union and hardware failure were also assessed.
RESULTS
In the immediate post-operative period, fracture instability was seen in 1 (6.7%) patient which resolved by 2 weeks. Mild occlusal discrepancy was also noted in 1 (6.7%) patient. Wound dehiscence was seen in 5 (33.3%) patients and all resolved by local measures. 1 (6.7%) patient developed post-operative nerve paraesthesia. Immediate post-operative radiographic evaluation demonstrated optimal reduction in all cases with no inferior border gaping. No case of infection, hardware failure, non-union and mal-union was noted.
CONCLUSION
Within the limitations of the study, 1.7 mm 3D strut plate was found to be effective for management of non-communited mandibular angle fractures.
目的
我们报告使用1.7毫米三维（3D）支撑钢板治疗下颌角骨折的经验。
方法
本前瞻性研究纳入了15例下颌角骨折患者，采用经颊套管针使用1.7毫米3D钢板进行治疗。在术后72小时、2周、6周和12周对患者进行评估，观察骨折稳定性、咬合情况、软组织肿胀、感染及术后下牙槽神经损伤情况。还评估了其他并发症，如伤口裂开、骨不连、畸形愈合及内固定失败。
结果
术后即刻，1例（6.7%）患者出现骨折不稳定，2周时骨折稳定。1例（6.7%）患者也出现轻度咬合差异。5例（33.3%）患者出现伤口裂开，均通过局部处理愈合。1例（6.7%）患者术后出现神经感觉异常。术后即刻影像学评估显示所有病例均实现了最佳复位，下颌下缘无张开。未发现感染、内固定失败、骨不连及畸形愈合病例。
结论
在本研究的局限性范围内，发现1.7毫米3D支撑钢板对治疗非粉碎性下颌角骨折有效。
